For this case we have that by definition, the volume of a rectangular prism is given by:
Where:
a: Long
b: Width
c: High
Prism 1:
Prism 2:
Thus, the total volume is:
Answer:
Y = 9
7y - 10y = -3y
bring down the 9 = -18 so
-3y + 9 = -18
9 - 9 = 0
- 18 - 9 = - 27
- 3y ÷ - 3 = y
- 27 ÷ -3 = 9
therefore y =9
When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.
The answer is yes they are congruent because if you flip the second one they are the same.
I hope this helped :)
